Miniature rose plant named `JACnuye`

ABSTRACT

A miniature rose plant having bright orange to orange-red flower color; pointed ovoid bud; small, two-inch flowers; and dark green, glossy, powdery mildew resistant foliage.

The present invention relates to a new and distinct variety of roseplant of the miniature rose plant class which was originated by me bycrossing the variety `MACnewye`, U.S. Plant Pat. No. 5,428, with anunnamed seedling (unnamed seedling×MORpints).

The primary objective of this breeding was to produce a new rose varietyhaving a miniature rose plant habit; a bright orange to orange-redcolor; pointed ovoid bud; small flowers two inches in diameter; and darkgreen, glossy, disease resistant foliage. The objective wassubstantially achieved, along with other desirable improvements, asevidenced by the following unique combination of characteristics thatare outstanding in the new variety and that distinguish it from itsparents, as well as from all other varieties of which I am aware:

1. A miniature (dwarf) plant habit;

2. Pointed ovoid buds;

3. Small, two-inch flowers;

4. Bright orange-red color;

5. Dark green, glossy foliage; and

6. Resistance to powdery mildew.

Asexual reproduction of this new variety by cuttings as performed atWasco, Calif., shows that the foregoing and all other characteristicsand distinctions come true to form and are established and transmittedthrough suceedling propagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor descriptions using terminology in accordance with The RoyalHorticultural Society (London) Colour Chart, except where ordinarydictionary significance of color is indicated.
